King played the yellow-haired prostitute Goldie in the first movie and will return to portray her twin sister Wendy, says The Hollywood Reporter. Chung, meanwhile, will be stepping into the roller-skates of deadly little Miho, a role that was originally depicted by Devon Aoki in the 2005 film.

Although production is now underway, casting is still in session for many key roles. The part of Ava -- the "Dame to Kill For" in question -- was originally written for Angelina Jolie, but now the role remains unfilled. There's also the matter of Michael Clarke Duncan's character Manute, who is featured prominently in Dame; the actor's recent passing will call for a recast.

The big question mark, however, is Dwight, who was formerly played by Clive Owen. While sources suggest the actor is returning, the character has yet to undergo facial reconstructive surgery in this story and thus appears completely different, leaving some fans wondering if another actor will need to step in at some point.

Fortunately, Sin City's Rosario Dawson, Jessica Alba and Mickey Rourke have all been confirmed for the sequel, so their characters are already settled.
